To all 'whom 'it may concern:

Be it known that I, HARRY W. SHEEHY, citizen of the United States, residing at Akron, in the county ofSummit and State of Ohio, have invented certain new and useful Improvements in Fuse-Boxes, of which the following is a specification.

The object of the present invention is the provision of an improved fuse box embodyL lng a novel construction which admits of a burnt out fuse being quickly and easily replaced Without any delay or loss of time, such delay not only being inconvenient but being; sometimes accompanied by danger. as Where a Astreet car provided with air brakes is on a down grade and the fuse in the circuit of the motor operating the air compressor becomes ruptured.

The invention has for its further object to accomplish this result by means of a fuse box which is simple and durable in its construction and enables the burnt out or ru tured fuses to be readily replaced Without t e necessity of shutting olf the current or without danger of contact with a live wire.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to behad to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a fuse box embod the invention. Fig. 2 is a longitudina sectional view through the same. Fig. 3isaplan view of the casing Fi .4isa detail yiew of one of the connecting b ocks.

Corresponding and like parts are referred to in the followlng description and indicated in all the views o the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates the casing and 2 the cover therefor, the said members being formed of porcelain, hard rubber, or other material of a similar nature. Diagonally opposite corners of the casing are provided with the openings 3 designed to receive screws or similar fastening members for securing the casing to a wall, panel, switch-board, or'other sup ort. Slots 4 through whichthe wires 5 of t e main circuit extend are provided at op osite ends of the and the sides of t ey casing are fingir receiving depressions 6 which enable a m gripv to be readily obtained upon the cover when removing the same or placing it in position. A connecting block 7 is secured within the casing at cach end thereof by means of a screw 8 passing through the bottom of the casing and engaging the block, and one end of each of these blocks 7 is formed with a longitudinal opera .ing 9 for receiving the wire 5 which is clamped within the opening by means of a set screw 10. The opposite end of each of the connect' blocks 7 is provided with a socket forme by a pair of spring jaws 11 which project upwardly and downwardly below the block, the downwardly projecting portion being loosely received within a recess 12 in the base, the said recesses coperating with the screws 8 to properly position the aws. 1 The cover 2 is reversible and is provided upon both of its faces with a pair of outwardly projecting parallel ribs 13 between which a fuse wire 14 is arranged, one of the wires being located upon each side of the cover and the said wires be' protected against inju b means of the ribs. site ends of ltivle se wires 14 are engaged bv contact members or binding posts 15 which project outwardly from the cover, those inding posts upon the inner face of the cover being designed to enter the sockets defined by the spring jaws 11 so as to introduce the fuse wire connect' the same into the `main circuit. Each o the binding posts comprises a screw 15l which extends thro h the cover, a collar l5b which is t ed upon the screw for cooperation with the head thereof to retain thescrcw in position upon the cover and a head 15 provitllled for clamping the fuse wire against the co ar.

One of the connecting blocks 7 is disposed somewhat nearer the adjacent end of the casing than the opposite connecting block and the binding ts disposed upon the cover are arrange in a similar manner so that when the heads g; tllie inlper set of binldingostsareengag ytejawsllte cove? will fit accurately upon the casing. It will be observed however that the binding posts upon the opposite sides of the cover are arranged in a reverse manner so that when the cover is reversed to introduce the opposite fuse wire into the circuit it is necessary to revolve the cover endwise as well as transversely. With this construction the two binding posts at each end of the cover are thrown out of alinemant with each other so that there is no danger of the screwsl Oppobeing brou ht into electrical connection. When one o the fuses burns out or becomes ruptured for any reason the cover 2 is removed from the casing and again applied thereto in a reverse manner as reviously set forth so that the opposite set o inding posts enter the sockets dened by the s ring jaws 11 and the o osite fuse is intro uced into the circuit. e fuse whichwas previously burnt out may then be readily re laced without the necessity of cutting oii t e circuit or without danger of coming into contact with a live wire. At this point it may be noted that the free ends of the spring jaws 11 are notched at 11 to receive the fuse wire so that there is no danger of cutt' the wire when the cover is lace in position.

Having thus described t e invention, what is claimed as new is:

l. In a fuse box, the combination of a casing, a reversible cover for the casing, a fuse wire pon each side of the cover, and means for introducing either of the fuse wires into the circuit.

2. In a fuse box, the combination of a casing a reversible cover for the casing, a pair of spaced ribs projecting from each slde of the cover, a fuse wire upon each side of the cover, said fuse wires belng arranged between the ribs, and means for introducing either of the fuse wires into the circuit.

3. In a fuse box the combination of a casing, connecting blocks within the cas' a reversiblecover, and a fuse upon each si e of the cover, either of the fues being) adapted to be introduced into the circuit` etween the connecting blocks.

4. In a fuse box the combination of a casing, connecting blocks arranged within the` casing,'a reversible cover for the easing, contact members projecting from opposite sides of the cover and fuse wires connecting the contact mem ers upon veach side of the cover, either set of the contact members beings designed to engage the connecting bloc when the cover is in position.

5.' In a fuse box the combination of a casing, connecting blocks arranged within or severing the casing and formed with sockets, a reversible cover for the casing, contact members project' from opposite sides of the cover, and a use wire connecting the contact members upon each side of the cover, either set of the contact members being desi ed to enter the sockets of the connecting b ocks when the cover is in position.

6. In a fuse box the combination of a casing, connecting blocks arran ed within the casing and provided with spring jaws, a reversible cover for the casing, contact members projecting from opposlte sides of the cover, and a fuse wire connecting each set of contact members, either set of contact members being designed to engage the spring jaws of the connecting blocks when the cover 1s in osition.

7. a fuse box the combination of a casing, connecting blocks arranged within the casing, a reversible cover for the casing, contact members projecting from opposite sides of the cover, a fuse wire connecting the contact members upon each side of the cover, and ribs projecti from opposite sides of the cover, the said digs receiving the fuse wires between them and either set of contact members be' designed to engage the connecting blocks w en the cover'is in position.

8. -In a fuse box the combination of a casing, connecting blocks arr ed within the casing and formed with soc ets, a reversible cover for the casing, a pair of spaced ribs projectin from each side of the cover, contact mem ers projecting from each slde of the cover, and a fuse wire connecting the contact members upon each side of the cover, the said fuse'wires bei disposedA between the ribs and either set o the contact members be' designed to engage the connecting blocks w en the cover is in osition.

In testimony whereof I a my signature in presence of two witnesses.

HARRY W. SHEEHY.
